Adding to the laundry list of Nike Free's we've seen over the last couple days, Nike revealed their high intensity training shoe the Free Hyperfeel TR.

As expected, the Nike Free Hyperfeel TR was designed with natural motion at the forefront. Weighing in at just 10 oz, the Hyperfeel TR is Nike's lightest training shoe ever and was designed for high-intensity training. Combing three of Nike's most innovative technologies, Flyknit, Lunarlon, and Nike Free, the Hyperfeel TR delivers the same low profile design to keep the foot closer to the ground for a more natural stance. Flyknit technology was used to develop the upper and act like a lightweight second skin for superior comfort, breathability and support. The insole is comprised of Nike's Lunarlon technology for soft and responsive cushioning.

Nike Flyknit was first used in running shoes back in 2012 and has recently been incorporated into basketball shoes when developing the Nike Kobe 9 Elite, so it's no surprise Nike would develop a trainer comprised of their prize technology.

Check out the interview with Nike Athletic Training's new Footwear Design Director, Nathan VanHook as he gives further insight and details into the development behind the Nike Free Hyperfeel TR and the updated Nike Free Trainer 5.0.

The Nike Free Hyperfeel TR will be available May 1 at Nike.com and select retailers worldwide.
